Filed: 1925-06-17
Abstract: 236,205. Chicago Pneumatic Tool Co., (Assignees of Hoffman, L. F.). June 24, 1924, [Convention date]. Regulating or controlling.-A fluid compressor B is driven by an internal combustion engine with a normally open throttle valve in the fuel intake, which is moved towards its closed position by fluid pressure means when the compressor is unloaded. This is accomplished by a pilot valve C' connected to receiver pressure by the pipe c, and discharging pressure fluid, when the receiver pressure reaches a predetermined value, through a pipe c<1> to actuate the unloading valve D, and through a branch pipe c<2> to the actuating device for the throttle. The valve 7 is supported on a pivot 8 in a cylindrical casing 4 secured between the carburetter and the intake manifold. A coiled spring 9 tends to hold the valve open, and the spindle 8 carries an arm 12 engaged by a projection on the piston 16 operated by the pressure fluid from the pipe c<2>. An adjustable pin 18 limits the movement of the valve. In the working of the device the pressure fluid which operates the piston 16, and valve 8 is relieved by the valves when the required pressure is below the predetermined value and the parts 16, 8 are restored to their normal positions.

Abstract: A process for the production of terephthalic acid by interaction in the liquid phase of an aliphatic para disubstituted benzene and molecular oxygen in the presence of bromine and a catalyst containing cobalt or manganese at a temperature above 165 DEG  C. is characterised in that there is added at least one of the following:-nickel, copper, zinc, tin and iron, or a compound of one of these metals, in such amount as provides in the reaction mixture a concentration of nickel exceeding 100 parts per million, or a concentration of copper between 25 and 150 p.p.m., or of zinc between 1,000 and 5,000 p.p.m., or of tin between 100 and 1,000 p.p.m., or of iron not more than 1,000 p.p.m.  Preferably an excess of oxygen is maintained continuously in the reaction system.  Preferably a catalyst containing both cobalt and manganese is used and the reaction is carried out in an inert medium such as acetic acid or water.  The reaction may be carried out in titanium, silver, or glass lined equipment, or in steel reactors, e.g. of nickelsteel alloys. Examples describe the production of terephthalic acid from mixtures of p-xylene, glacial acetic acid, cobalt bromide, manganese bromide or acetate, and various proportions of nickel carbonate or acetate, copper sulphate, zinc acetate, stannous chloride, and ferric acetate. When the reaction is carried out in a steel reactor it is not necessary to add iron directly but the content of iron in the reaction mixture should be controlled within the specified limit, e.g. by by-passing mother liquors through an ionexchange resin before re-cycling.  Specifications 737,439, 787,937, 804,612, 807,091, 810,020, 841,246 and 850,960 are referred to.

Title: Method for magnetic recording and reproducing of high-frequency signals,in particular television picture signals as well as sound and/or synchronization signals
IPC: H04N9/86
Filed: 1966-03-23
Abstract: 1,113,515. Video recording & playback. LOEWE OPTA A.G. 23 March, 1966 [23 March, 1965], No. 16331/66. Heading G5R. Video, sound and control signals are recorded on and reproduced from a single magnetic tape channel by frequency modulating a carrier with the video signal and separately amplitude modulating two carriers spaced apart in the frequency spectrum below the frequency of the lowest frequency modulation signal with the sound and control signals. In the arrangement shown, the signals are recorded on oblique tracks on'the tape by a single magnetic head 4, rotating on a head wheel coupled to a braking disc 9. The video signal is amplified in unit 26 and frequency modulates a carrier in unit 27 which supplies an output signal in the band 0À5-4À5 Mc/s. to a recording amplifier 28. The picture sync. signal is separated from the video signal in units 30, 31 and triggers a 10 Kc/s. oscillator 32 to produce a burst of 10 Kc/s. signal during the occurrence of each frame sync. pulse. This signal amplitude modulates in unit 35 the 80 Kc/s. output of oscillator 33, which is also the erasing signal, and the modulated signal is applied to the input of recording amplifier 28. The sync. pulses are also applied, with pulses generated by the rotation of the brake disc 9, to a phase detector 39 which generates a signal to synchronize via braking unit 10 the speed of rotation of the head wheel and the sync. signals. The output frequency of the 80 Kc/s. erase oscillator is doubled in unit 36 to provide a 160 Kc/s. carrier which is amplitude modulated in unit 38 with the audio signal, and this modulated signal is combined with the other two modulated signals in recording amplifier 28, the output of which is connected to the recording head 4. During playback filtering and demodulating units recover the separate signals, the control signals being used to control the speed of rotation of the playback head wheel.

Title: Reduction of oscillation by anti-oscillation means
Inventor: BSCHORR OSKAR
IPC: F16F7/10
Filed: 1970-04-07
Abstract: 1,260,457. Vibration damping. MESSERSCHMITT BOLKOW - BLOHM G.m.b.H. 7 April, 1970 [14 April, 1969], No. 16331/70. Heading F2S. To reduce or eliminate vibrations of a body, a transducer such as an accelerometer is employed to sense the vibrations and the transducer output is used to control the generation of a force which is made to act directly between the body and an inertia mass, the force being of such magnitude and direction as to nullify the sensed vibrations. Several examples of the application of this principle are disclosed, viz. (a) a coil carried by the body is associated with a magnet which is connected to or constitutes the inertia mass, the coil being energized by the output of a transducer sensing the body's vibrations; (b) a like system in which the coil and magnet are replaced by a suitable magnetostrictive, electrostrictive or fluid-operated, e.g. piston and cylinder device; (c) use of air cushions or air pressure as the force-generating means. In the last-named case, two plates which may be of glass and constitute the panes of a double-glazed window required to be sound-insulated, constitute effectively the body and the inertia mass. The air between them constitutes the means for causing a vibration-eliminating force to act between them. Heater wires are fitted in the air space and the transducer output, by controlling the energization of these wires, determines the temperature and hence the pressure of the air. It is also possible, in the case of moving bodies such as aircraft, to cause the ambient air to function as the inertia mass of the system, the force-generating means being air jets which apply a sucking or blowing action to the surface of the moving body.

Abstract: 722,137. Electric clocks. LIP SOC. ANON. D'HORLOGERIE. June 30, 1952, [Feb. 19, 1952], No. 16429/52. Class 139. An electric clock having an electro-magnetically maintained oscillator is characterized in that a pivoted lever is adapted to be angularly shifted by the oscillator when the latter moves beyond a predetermined amplitude, said shifting urging the lever against either of two stationary abutments whereby the movement of the oscillator is arrested. As the balance A, Fig. 4, swings clockwise a cam A1 on the balance staff moves a spring conductor C against a contact C1 to energize the electromagnet B which impulses the balance A in the usual manner. A pin A2 on the balance A co-operates with the forked end D4, D5 of a lever D, pivoted at D1, and lying between two pins El, E2. Should the balance receive a shock sufficient to cause it to swing too far in one direction the pin A2 will engage the outside of the limb D4 or D5 of the forked lever D which is thereby moved until arrested by the appropriate pin E2, E1 so locking the balance. An overswing of the balance will not result in a closure of the circuit of the electromagnet B.
